There are many cases where non-human animals have adopted children not their own, sometimes even from other species. For examples, see the Moses the Kitten, Kanzi the bonobo and all the gay penguins who adopted orphaned penguin chicks.

What if you want to raise children, but can't have children of your own? Do children whose biological parents are unsuitable or even dead not deserve to be raised by loving parents, too?

If you see your children as nothing more than vehicles for your genes, you fail as a human being and do not deserve to reproduce.

Wrong. 'Cuck' is unknowingly raising another man's kid as your own. Adoption is an eyes-wide-open act.

And it's not the genes that make a kid MY kid. It's that he uses my swear words, tells my jokes, complains about my music.

But this is just an observation from having raised three kids to the adult side of college. So, you can go on telling me The Truth about parenting, but that's kind of like a virgin who watches a lot of porn telling me what sex is like.

Think about it. Anytime a woman deigns to give them attention, they lose the woman to a guy who is a better guy, anytime they find a girl attractive she either doesn't know and goes to her lover or she isn't into the incel. And goes to her lover.

And if lions built the internet you would be noted for your common sense.
But human instinctive behavior caused a human civilization that outcompeted all the other primates and made an internet. So fuck your weak gene bullshit ignorance.

Are you trying to give us a hint that the woman doesn't really bring me into her bedroom to fuck her like a cat in heat just because she doesn't have $12.34 to pay for the pizza, plus tip? I'm absolutely shocked to hear that, I tell you!

I don't think comparisons to lions will help your case. First of all lions DO raise their cubs communally and their social structures don't favour the males as much as you like to think they do. Second the lions that murder cubs are always those who invade a pride and try to take it over. Whether born into the pride or invasive nomads the male lions are essentially gladiators for territory disputes. They're ironically something of a sacrificial lamb, they lose that position once a stronger lion comes along or are expelled by the lionesses once the males "age out" in an inversion of "manosphere" desired practices. Also lionesses don't just "let" their cubs get killed. They fight or they trick the invaders.

Yes, male lions do occasionally kill the cubs of female lions which they hope to mate with, but they basically have to not get caught and not leave behind a corpse which smells of them. Female lions are neither passive nor stupid; if she has any reason to believe that a male has killed any of their cubs, she will reject him - violently. And if her sisters (whether genetic or pridemates) get involved, he may well end up dead.

I would like to add, you actually can make the two ideas K and I had work. Mine is a little easier. See, here's the thing. First, you talk with your girlfriend up front about a fun little fantasy you want to play out, and if she agrees, you stop and pick up a pizza on your way home from work. Then . . . have fun with it.

K's idea is a little harder, because now you need a girlfriend who's okay with a threesome, but again, talk with her about it first, and if she's cool with it, and one of her friends is cool with it . . . have fun with it.

Happening "naturally" on its own, like in porn movies? Ah, nope. Remember, even porn movies are scripted. Even if most of the time the script writing is horrible.
